# Slackware build script for qodem

# Written by B. Watson (urchlay@slackware.uk)

# Licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.

# Notes:
# - Package includes both terminal (qodem) and X11 (qodem-x11) binaries.
# - qodem-x11 always builds with its bundled copy of pdcurses, regardless of
#   whether our PDCurses package is installed. Perfectly OK, just worth
#   mentioning why PDCurses isn't a dependency.
# - Two choices for ssh support: build with bundled cryptlib (like syncterm
#   does), or run an external ssh command. Upstream's default is the latter,
#   I won't change it. Plus, using the ssh binary has the useful side effect
#   of respecting your ~/.ssh/config.

### this builds the terminal binary (qodem):
buildit

### now start over, prepare to build the x11 binary (qodem-x11):
make distclean

# we have to build these separately, for parallel builds (-jN, N>1):
make -C lib/pdcurses
make -C lib/upnp

# sub-projects built, now we can build qodem-x11:
buildit --enable-x11

### everything else:

# This script isn't useful. All it would ever do is "exec qodem-x11", since
# our package includes that.
